Coils for critical applications
At Alleima, we specialize in high-precision wire forming processes—including stranding, twisting, and coiling—to support demanding applications in medical devices, electronics, and advanced assemblies. From simple single-filar helicoils to complex multi-filar constructions, our wire configurations are engineered for reliability, consistency, and tight geometric control. From single-filar helicoils to intricate multi-filar constructions, our wire configurations are engineered for reliability, consistency, and precise geometric control.
Whether your application requires micro-coils for sensor leads or twisted conductors for signal transmission, our expertise enables the development of highly functional, application-ready wire structures. With Alleima, you gain a partner committed to elevating performance and driving innovation in every strand.
Our expertise
Twisting
Twisting precisely aligns two or more wires in a controlled helical pattern. This configuration is essential for signal transmission, effectively minimizing electromagnetic interference (EMI) and cross-talk—critical factors in diagnostic and therapeutic medical devices.
Stranding and multifilar configurations
Stranding combines multiple wires into a uniform helical bundle, delivering flexibility, mechanical strength, and redundancy. Single strands can be joined into multi-filar or micro-ribbon cables for multichannel signal, sensing, or power applications—streamlining assembly in medical devices.
Choose from a wide range of options: strand color coding for easy assembly, tailored bond strength, and the ability to combine different alloys within a single cable. Our cables are available in diameters from 0.018 mm to 0.25 mm and can be supplied bare, individually coated, or overcoated with polyimide, polyester-imide, polyurethane, or PTFE.
From continuous to selectively bonded lengths, every configuration is engineered for precision, reliability, and performance—enabling complex forms such as coils and supporting demanding applications like telemetry, thermocouples, and ground wires. With Alleima, you get wire solutions built for your requirements.
Coiling
Coiling shapes wire into tightly controlled helical forms, from micro-scale, free-standing inductive coils to complex multi-filar helicoils for structural or signal applications. Our coiling processes accommodate a wide range of geometries, pitches, and wire types, including both bare and polymer-coated materials.
